IMPROVEMENT IN FIXING- PUDDLING- AND BOILING-FURN'ACES.

'lhe Schedule referred to in these Letters Patent and making-part of the same.

To all whom t't may concern:

Be it known that I, MORGAN Z. EVANS, of Ormsby, in the county of Allegheny, and -State of Pennsylvania, have invented a new and useful Improvement in Fixing or Repairing Puddling-Furna'ces; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to paddling and boiling-furnaces, and applies to the process called by furnace-men xing, which is performed-as occasion may require, in the way of repairs, after the furnace has been in operation for some time,'when not in use; and

It consists in the use of curved 'plates in the furnace, which, when placed together, correspond in form to the shape of the'furnace, on the outside of which the fixing-mortar7 is placed. y

In the accompanying plate of drawing- Figure 1 represents two curved plates standing edge wise, and placed together as they stand when in use in lthe furnace, representing the shape of the furnace.

Figure 2 shows the inner side of one of the plates.

Similar letters of refeence indicate corresponding parts.

Pnddling-furnaces are usually fixed with pulverized ore, or a sort of mortar made of such ore,'put on by what are called dabbers,7 a kind-oftool for that purpose. Thisis a tedious and imperfect operation, and requires about double the quantity of the' pulverized ore that I find it necessary to use by my improved method.

In carrying out my invention, I use the platesAA, which, when placed on edge, as represented 'in the drawing, determine the shape of the furnace on the inside.

These curved plates are placed on the hearth, and the pulverized ore-mortar is placed around them in a compact mass.

When the fixing has become suciently hard to allow of the removal ofthe plates, they are drawn ont one at a time `by hooks made for the purpose, which are inserted into holes in the lugs B B, on the inside, as seen in the drawing.

By this 4method of fixing a Vast amount of time and about one-half of the ordinary expense in ore are saved, as compared with the old system.

Having thus described my invention,

I claim asnew, and desire to secure by Letters Patent- In combination with a puddling` or boiling-furnace, the curved plates A A, substantially as and for the purposes herein shown aud'described.

The above specification of' my invention signed by me, this 27th day of February, 1869.

` MORGAN Z. EVANS.
